Build an 'NCLEX Question of the Day' content page — the payoff of a social post. Reproduce EXACTLY this question and content; do NOT invent a different question. Eyebrow: 'NCLEX Question of the Day' with the date 'June 1, 2026'. Question stem: 'A nurse is caring for four patients on a medical-surgical unit. Which patient should the nurse assess first?' Four options, single-best-answer: A) A patient with heart failure who has gained 3 lb (1.4 kg) overnight and reports mild dyspnea when walking to the bathroom. B) A patient 1 day post-appendectomy with a temperature of 99.2°F (37.3°C) and pain rated 4/10. C) A patient with type 2 diabetes whose fasting blood glucose is 186 mg/dL and who is requesting breakfast. D) A patient with chronic kidney disease whose potassium level is 6.8 mEq/L and who reports tingling in the fingers. The CORRECT answer is D. Include a 'Reveal the answer' interaction that shows D is correct, then a thorough rationale explaining why D is the priority (hyperkalemia > 6.0 mEq/L with paresthesias is a life-threatening emergency affecting cardiac excitability) and why A, B, and C are lower priority (expected/non-urgent findings). Include a 'Key Takeaway' callout box with this text: 'Hyperkalemia above 6.0 mEq/L is a medical emergency. When prioritizing patients, always assess for life-threatening electrolyte imbalances—especially potassium, which directly affects cardiac function. Neurological symptoms like paresthesias, muscle weakness, or paralysis indicate the imbalance is severe enough to affect cell membrane excitability. Remember: the heart is a muscle too, and it will be affected next.' Exactly ONE soft CTA near the end: 'Get a new NCLEX question every day — start free.'
